BROADCAST SEEDING-MACHINE SPECIFICATION forming part of Letters Patent No. 363,053, dated May 17, 1887.

Application filed January 15, 1887. Serial No. 224,407.

To all whom it may concern:

Beit known that l', CALEB EAsrERLrNG, a citizen of the United States, residing at Friendswood, in the county of Hendricks and State of Indiana, have invented a new and useful Improvement in Broadcast Seeding-Ma chilies, of which the following is a specification.

My invention relates to an improvement in broadcast seeding-machines of that class in which the seed is carried in a suitable recepta cle secured to the body of the operator, and is thrown by means of a revolving disk.

The objects of my improvements are to provide a seed-throwing disk from which the seed shall be evenly distributed, in nearly a hori- Zontal plane, in front and to each side of the operator, but which shall throw no seed backward against his body; to provide means for controlling the throwing` of the seed more or less to one side, and to provide a screen for separating foreign matter from the seed within the hopper, which screen may be quickly adjusted for use or dispensed with at the will of the operator, all as hereinafter fully described.

The accompanying drawings illustrate my invention.

Figure l is a vertical section, the throwingdisk being shown in elevation. Fig. 2 is a transverse section at a, Fig. l. Fig. 3 is a partial plan, as seen from below, at b. Fig. 4 is a section on an enlarged scale at c, Fig. l.

A is the hopper.

B is a bag-like extension of the hopper, which is removably secured in position by means of a rectangular hoop of wire, d, Fig. l, which is secured in the lower edge of the bag and engages lugs e c, secured to the inside of the hopper. v

C is the feed -wheel into which the seed passes from the bottom of the hopper through an opening, f, Fig. 2, which is covered more or less, to control the flow of seed, by a slid ing valve, h. 'W heel C is mounted on a shaft,

fi, on which is also mounted the internal gearwheel, j.

D is a tapering chute which conducts the seed from the feed-wheel to the throwing-disk E. The throwingdisk E is mounted on avergo tical inclined shaft, k, which is revolved by (No model.)

means of the bevel-gears Z andm, shaft n, pin ion o, and internal gear-wheel, j.

F is a cylindrical shield mounted centrally on disk E for the purpose of keeping the seed away from the center.

The throwing-disk is arranged to revolve from left to right, as indicated by the arrows, Figs. 2 and 4t. Secured to the upper surface of disk E are a series of radial wings, r, s, and t. The outer ends of the upper edges of said radial wings are connected and the spaces between them covered by a thin annular plate, H.

For the purpose of retaining the seed so that it shall be discharged at diii'erent points, wings r, s, and t are arranged at different angles to the path of rotation of the disk, as indicated by the dotted radial lines in Fig. 4t. It will be observed that the wing i is inclined backward, while wings s and i are inclined forward, wing tbeing inclined forward more than wing s. This arrangement of the wings has been found by careful experiment to result as follows: The seed that falls from chute D onto the disk E and in front of wing o' will, as the disk is revolved, escape whenthe wing has reached the position shown in Fig. 4t, while the seed falling in front of the wings s and t, wing t being inclined at a greater angle than wing s, is retained longer and is evenly distributed over that portion of the circle embraced between the forward surfaces of wings fr and t, the whole escaping by the time that wing t reaches the position shown.

For the purpose of regulating the point of discharge from the throwing disk toward either side,'ehute D is adjustably secured to the hopper by screws u u, passing through slot` ted holes c o in the chute. It is obvious that the seed will acquire sufficient momentum to overcome the resistance of the disk and the wings while passing over a certain space, so

per next the bottom. Said rod extends through leo the side of the hopper and is provided with thu1nb-1ever, x, by means of which it may be turned. Secured to rod w is a light frame inclosing a wire screen, y. When rod wis turned forward, the screen is thrown into the position for use, above the openingf, as shown n Fig. 1, and by turning the rod backward the screen is thrown iiat against the bottom of the hopper.

I claim as my invention- 1. In a broadcast seeding-machine, the conibination of the hopper, the feed-wheel, the 'ohute, the throwing-disk, and means for revolving said feed-wheel and throwing-disk, said throwing-disk being provided with radial wings securedto the surface thereof at different angles to the .path of rotation of the disk, substantially as and for the purpose specified.

2. In a broadcast seeding-machine, the combination, with the throwing-disk arranged to revolve, of the series vof vertical radial wings secured to the Working-face-of 'thedisk and arranged at different angles to thepath of rotation, one of said wings being inclined backward and the other wings being inclined forward 25 successively in a greater degree, substantially as specified. n

3. In a broadcast seeding-machine, the con1- bination, with the hopper, the feed-wheel, the throwing-disk having a series of radial wings 3o arranged at different angles, and means for revolving said feed-wheel and throwing-disk, of the chute arranged to conduct the seed from the feed-wheel to the throwing-disk and adjustably secured to the hopper, substantially 35 asand for the purpose specified.

4. In a broadcast'seeding-machine, the conlbination, with the hopper and the feed-wheel, of the rod w and screen y, al1 arranged in the manner and for the purpose speciiied.
